To all whom 'it may concern:

Be it known that I, GEORGE HEBER CARTER, a subject of the King ofEngland, residing at Richmond Hill, in the city of New York, Queens, andState of New York, have invented certain new Iself-lilling complish lare,

also to prevent .is .illed and the. suction is released, fand abarrel ofvarying diameter.

Y place, 'valves which and useful Improvements in Fountain- Pens, ofwhich the following is a full, cl'ear, and exact'specitication.

My invention relates to lfountain pens and particularly to that class ofsuch pens as contain within themselves the means whereby they may berefilled and which are called fountain pens. rIhe type of such pens towhich my invention relates is that wherein the cap of the pen acting asan exterior piston, draws the ink into the barrel through the nozzle.

The object of my invention is to produce a simple and economicalconstruction of such device and one that shall be simple in operationand have nolpassages which will be likely to clog up, and consequentlywill not get out of order and'will not need fre` quent cleaning.

Other and important objects which I acto prevent the dischar e of anysmall amount of ink which may e in the barrel, through the nozzle, whenthe cap is setto position to act as a piston and fill the barrel; alsoto prevent the further drawing in 'of ink when the barrel is filled; anyleakage of inkwhen the vsuction of the piston is released; and to effeetthese and other objects and advantages which will appear more fullyhereafter, my inventionconsists, among other things, in the employmentof a cap acting as an exterior pump piston and which I prefer toperforate, together with a barrel having a bore to permit such plumpaction to take combined wit oppositel-acting automatically check t einflow of ink when the flow when the suction is released. Such valves asare illustrated are a float valve for preventing further feeding whenthe4 barrel is filled, with means `for securely sealing the bore whenthe barrel is filled, a check valve for'preventing back flow when'thebarrel upon the barrel,

barrel is filled and the out-.-

One embodiment of my invention is illustrated in the accompanyingldrawing wherein- Figure 1 is an elevation of my -improved fountain penclosed, the cap being shown in section. Fig. 2 is a longitudinal section(the nozzle being in full lines) through the pen, the parts being in theposition they will assume in filling, and the pen being partiallyfilled. Fig. 3 is a cross-section through the perforated stem of the setvalve, barrel packin ring, and cap; vand Fig. 4 is a detail of the rearend of the barrel, filled with ink, with the float valve in sealingposition and the set valve sealing the end of the barrel.l

The barrel 1 of the pen is provided with a nozzle 2, equipped with anysuitable variety of feed bar. The cap 3, which is perforated at 4, forpurposes hereinafter more fully explained, lits snugly upon the nozzleend of the barrel. The barrel is reduced in diameter at its rear end fora distance of something like two-thirds of its length, and upon thisreduced part the cap 3 slides when acting as a piston. A ring packing 5of soft rubber or equivalent material is seated and securely held, as bycement,` etc., in a groove or channel 6, formed peripherally wall of thecap, while permitting the latter to slide thereon.

The barrel has a bore 7, formed in itsrear end, and the'inner wall ofthebarrel; adjacent such bore is tapered as at 8, to form a seat for theioat ball valve 9. The bore 7 opens into an enlarged bore 10, and.between such bores 7 and 10, a tapered seat 11 is formed in the sidewalls for the check valve 12, which has a correspondingly shaped taperedface. The outer end'of the bore 10 is screw-threaded and receives thethread'I ed stem 14 of a headed set valve 13. Such stem is formed withan external, longitudinal air duct 15, extending from the base of thevalve head to the inner end of the stem and which, when the head israised, free passa e of air 'from the interior of the barrel to t einterior of the ca The valvehead 'is intende to be manually operatedvand may be round or of other convenient shape externally. It shouldpermits ioo stem 14 may be of such length as that the l check valve willbe crowded to its seat by l permit the air to pass out. flhe check valveproduce bubbles and Ymay then be removed and the headed set the end ofthe barrel.

above have its face 16 formed into a good t with y readily in ink, suchas cork, wood, etc., and i of the barrel, as in connection ther1ng.washer I prefer to make of soft with the Check valve 12 it formsthe-means rubber, cork, or some suitable frictlon matefor sealing therear end of the barrel when F1511.v the latter is full of ink. To aidthis the If the cap 1s retained 1n position, some of I the enumeratedparts may be dispensed wlth 'and a practical pen remain, as, forinstance, the perforation in thecap may be ornltted, and the check valveand set valve and the loatvalve and its seat and the bore retained.

I claim: lo A fountain pen comprising a perforated, removable cap, abarrel provided' with T0 refill the bel-rel er reservoir, a bore at itsrear end, means for causing a tight lit between thecap and the rear endof the barrel, a loose check-valve and a seat therefor at tle outerl endof said bore, .in as far as it will e, and means for ho ding t e same toits seat During this pushing 1n 0f the cap the pgn- 'i after the barrelis filled which means are such stem when the set valve is seated.

' The o eration of my device is as follows: We wil assume that thebarrel has previously been used and that the ink has becomeSubstantially exhausted. A slight of ink will still remain, sufficientto forced outL foration 4, in its end should remain open to WlthdlWQflQm Operatlve P05115we Whle the barrel 1s belng filled. e alr pressureand v 2. fountain pen comprisinga perfowill prevent any passage of airinto the barrated, PemQVable Cap, a barrel PT0Vlded-W1th rel 'andconsequently any, discharge of ink 1 bore at lts Teal @Il means fol'Causlng a or bubbles through the nozzle; The cap betlght 5t between theCap and the real' end ing in its inner position, the nozzle is inof thebarrel, a iioat-valveand a seat there Sel-ted in the Supply of vink andthe nger for at the inner end of sald bore, a checkplaced over theperforation the end of ValVOalld 3..

Should therebe any occasion, however, for cleaning the barrel, nozzle, or otherparts, the set valve and fountam check valve may be removed and theparts able perforated cap, thoroughly washe by using the cap as a boreat' its rear end having a reduced inner portion and an enlarged,threaded outer portion, a peripheral packing on `.the rear end of said'barrel adapted to lit said c ap, 'a float-valve and a seat therefor insaid ore, a loose check-valve and a seat therefor at the outer end ofsaid bore, aset-valve and a seat therefor at the end of said barrel, anda threaded, perforated stem therefor ceases, and means for holding sameto its seat when the barrel is' filled.A

The float valve will preferably bei made of some material whichwill oat pen comprising a removadapted to seatl said check-valve when.the set valve is closed.
